I have cleaned the intake air control valve and it still is acting up. What should be my next step?
If you want this fixed seriously because mine was doing the same thing and people kept getting me to buy all this **** i didnt need for my 03 lancer es and all i did was unplugged the MAF (mass air flow sensor) and it was perfect all over again. I was pretty upset figering this out yesterday. Just unplug it and turn your car over and let it idle a min. If all symptoms go away buy a new MAF sensor from a parts dealer for like a buck eighty.

Check for
vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
===
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
===
Also remove carbon built up behind the EGR valve and the EGR passage tube.
===
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
===
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

Idling problems may be cause buy a number of issues. You may check out the fast idle control valve and PCV if they would need cleaning. You can check out the timing it may be advanced, that is why you feel that the car runs hard.

Your A/C unit is low on Freon, or you have a bad pressure switch. Turn on the Air Conditioner, with the engine running, & put it on Max. Open the hood, & see if the compressor is spinning. If it is not, then you need gas. You can buy refill kits at a local Walmart. If you have a leak, it may be a wasted $30. That is what I paid for a 22 oz. can of R-134A Freon. I had a dealer regas mine & put in a dye that they can find leaks with a black light. It may be cheaper in the long run. My drier, in front of the radiator has a leak. It will cost $460. to replace it.
